( Figures 1 View FIGURE 1 B, 5–6)

Cernosvitoviella aggtelekiensis Dózsa-Farkas, 1970: 247 –250, fig. 3, +5 photos. Cernosvitoviella goodhui Healy, 1975 . Syn: Schmelz & Collado 2010: 61. nec: Cernosvitoviella goodhui Healy, 1975 . Chalupský, 1992: 141. fig. 8. nec: Cernosvitoviella cf. goodhui Healy, 1975 . Rota 1995: 193 –194.

Material investigated: (in total 11 specimens), 8 specimens from site 7 (31.03.2014 and 16.05.2015), 1 specimen from site 8 (31.03.2014), 2 specimens from site 5 (27.03.2016).

Body 1.7–3 mm long, 180–240 µm wide at the clitellum, segments 21–23. Chaetae sigmoid with nodulus, up to 7–9 per bundle, 29–32 µm long ( Figs. 5 View FIGURE 5 C,D). Clitellum absent dorsally and ventrally. Only dark spindleshaped coelomocytes, slightly wider than in C. farkasi sp. n., 35–57 µm long and 9–10 µm wide in the middle ( Figs. 5 View FIGURE 5 E,F). In the prostomium, about 8 large rounded papillae are observable ( Figs. 5 View FIGURE 5 A,B). Two or three paired or unpaired nephridia preclitellarly, from 6/7 ( Fig. 5 View FIGURE 5 H). Seminal vesicle absent. Chloragogen cells 20–30 µm long ( Fig. 5 View FIGURE 5 G). Sperm funnel cylindrical, 45–70 µm long and about 2–3 times longer than wide. The collar tall, as wide as the body of funnel ( Figs. 5 View FIGURE 5 I,J, 6B). Sperm duct similar to C. farkasi sp. n. with a large dilatation ( Figs. 5 View FIGURE 5 I,J), but not as conspicuous and somewhat narrower (20–30 µm and 8–15 µm wide, vs. 30–50 µm and 17–26 µm in vivo in C. farkasi sp. n., respectively), moreover slightly closer to the male opening than in the new species. Male opening surrounded by glands, diameter about 20–30 µm ( Figs. 6 View FIGURE 6 A,C). Length of spermatozoa 35–40 µm, heads 15–20 µm ( Fig. 6 View FIGURE 6 B). Spermathecae ( Figs. 1 View FIGURE 1 B, 6D–F) extending into V–VI, ectal ducts (50–80 µm long and 8–9 µm wide), widened at the ectal orifice into 15–19 µm, no glands at the openings. Ampullae oval (50–70 µm long and 15–19 µm wide), filled with sperm.
